Newbie.. what CDP/DAC for Krell 400xi and ML SL3

Before reading Jond's comment; the first thing that came ot mind when looking at your current set up is to get some tubes or a "warm" sounding source in there.

You may be headed for a very "sterile" analytical sound that is uninvolving.

Thanks for your reply. Actually doing more research right now..
- in some other threads, folks suggest 400xi is best go for XLR
- I found that Jolida actually carries a JD700 dvd play (tube + XLR)
- Though people say JD100 sounds better than JD700...
So, among these two, any suggestions? Or there are more options?

Naim CD5i. ~ $1000 used.

I just got a 400xi in my system this week. I haven't heard it in my system with another source, but it does sound very nice with the JD100, and Maggie 1.6s. I also replaced the 12AX7s in the Jolida with RCA 5751s, which are even more laid back than the 12AX7s.
I did hear the 400xi at the dealer's in single ended/RCA mode and in Balanced/XLR mode. XLR was louder, but I couldn't tell if it was better or not.
Good luck

Ktang, please let me have some feedback on either Jolida CDp with your 400xi. A while back,I used XLR connections from the KAV 280 CDP to the 400 xi and it was a day and night difference in term of not only dynamic (+ 6db)but details and tonal balance. I sold the Krell CDP280 for a personal taste in matching my system between black and silver. Just got back from Tweeter, Sade never sounds so warm and real with 400xi and the SACD standard and ML. I was about to buy the Jolida Jd100 or the Apollo but I believe nothing better than 400 xi and SACD combination running in XLR connection. I have decided I have to wait another 6 months or so to get the SACD at the authorized dealer but it will worth the wait. I have to live with the Rotel 1072 for now which is not really a good match for 400xi at all.
